Answer:Then a few days later the activity of the sample will be due to have more of Nuclides Y than X

Explanation:

This is because  half life of nuclide X is about a day which is less than Y having half life of about a week, After a few days, we would observe that  X would have  disintegrated more while Y will still be predominant since it disintegrate slower than X. The time it takes for X to disintegrate will always be faster than Y.

Need help with balancing equations
solniwko [45]

The balanced equation of the reaction shows that the mole of atoms on both sides of the reaction are equal.

<h3>What are balanced chemical equations?</h3>

Balanced chemical equations are equations in wgich the moles of each species on both sides of the reaction are equal.

To balance chemical equations, numerical coefficients are placed in front of the species in the reaction.

The balanced equations of the reaction are as follows:

3Pd + 4H_3PO_4 \rightarrow Pd_3(PO_4)_4 + 6H_2 \\

C_{11}H_{24} + 17O_2 \rightarrow 11CO_2 + 12H_2O \\

2Al(HCO_3)_3 + 3H_2SO_4\rightarrow Al_2(SO_4)_3 +6CO_2 +6H_2O \\

Therefore, the balanced equation of the reaction shows that the mole of atoms on both sides of the reaction are equal.

Elis [28]

C21H30O5  is its molecular formula

The hydroxyl groups at positions 17 and 21 and the oxo groups at positions 3, 11, and 20 are substituted in the C21 steroid cortisone. Both a mouse and a human metabolite, it serves a purpose.

<h3>Molecular formula: What is it?</h3>

A chemical formula is a way to communicate information in chemistry about the proportions of atoms that make up a specific chemical compound or molecule. Chemical element symbols, numbers, and occasionally other symbols like parentheses, dashes, brackets, commas, and plus and minus signs are used to represent the chemical elements.

A molecule's molecular formula reveals which atoms and how many of each kind are included within it. No subscript is used if there is just one atom of a certain kind. A subscript is added to the symbol for an atom if it contains two or more of a certain type of atom.
